The Corgi H2GO is a RC card powered by a fuel cell that gets refilled with hydrogen extracted from water. Like the previous model, the H-Racer, it uses solar-powered electrolysis to do it. Unlike the straight-line-only H-Racer, however, the H2GO is a real RC car that can actually turn left and right. Playing Dr. Manhattan will set you back $255. [Corgi via Pocket-Lint]
